The research shows that collective strategies with master-slave mechanism (CSMSM) defeat tit-for-tat and other well-known strategies in spatial iterated prisoner's dilemma. A CSMSM identifies kin members by means of a handshaking mechanism. If the opponent is identified as non-kin, a CSMSM will always defect. Once two CSMSMs meet, they play master and slave roles. A mater defects and a slave cooperates in order to maximize the master's payoff. CSMSM outperforms non-collective strategies in spatial IPD even if there is only a small cluster of CSMSMs in the population. The existence and performance of CSMSM in spatial iterated prisoner's dilemma suggests that cooperation first appears and persists in a group of collective agents.<\/p>","DOI":"10.4018\/ijsir.2021100103","type":"journal-article","created":{"date-parts":[[2021,10,8]],"date-time":"2021-10-08T09:13:20Z","timestamp":1633684400000},"page":"45-56","source":"Crossref","is-referenced-by-count":0,"title":["Collective Strategies With a Master-Slave Mechanism Dominate in Spatial-Iterated Prisoner's Dilemma"],"prefix":"10.4018","volume":"12","author":[{"given":"Jiawei","family":"Li","sequence":"first","affiliation":[{"name":"University of Nottingham, Ningbo, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Duncan","sequence":"additional","affiliation":[{"name":"University of Stirling, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingpeng","family":"Li","sequence":"additional","affiliation":[{"name":"University of Stirling, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruibin","family":"Bai","sequence":"additional","affiliation":[{"name":"University of Nottingham, Ningbo, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","container-title":["International Journal of Swarm Intelligence Research"],"original-title":[],"language":"ng","link":[{"URL":"https:\/\/www.igi-global.com\/viewtitle.aspx?TitleId=290279","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,6]],"date-time":"2022-05-06T14:45:36Z","timestamp":1651848336000},"score":1,"resource":{"primary":{"URL":"https:\/\/services.igi-global.com\/resolvedoi\/resolve.aspx?doi=10.4018\/IJSIR.2021100103"}},"subtitle":[""],"short-title":[],"issued":{"date-parts":[[2021,10,1]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2021,10]]}},"URL":"https:\/\/doi.org\/10.4018\/ijsir.2021100103","relation":{},"ISSN":["1947-9263","1947-9271"],"issn-type":[{"value":"1947-9263","type":"print"},{"value":"1947-9271","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,10,1]]}}}
